In order to establish simple and rapid testing methods for antibiosis of the rice plant to the green rice leafhopper, three testing methods, germinated seedling, young seedling and leaf blade method were studied. A germinated seedling in a test tube was used for the first method. A young seedling in a plastic cylinder was used for the second method. A cut leaf blade in a test tube was used for the third method. The survival ratio of the nymphs fed on test plants was examined in these tests. Although it fluctuated largely, it was shown that resistant varieties can be distinguished from susceptible varieties. Both testing methods using the seedlings seemed to be suitable for the screening of resistant varieties in any season, but unsuitable for the selection of crossing progeny because it was difficult to use the rice seedling for supplementary examination or breeding after testing. The leaf blade testing method could be used for various tests with attention to the survival ratio fluctuation, namely, screening of varieties, selection of crossing progeny. Consideration of the merits and demerits of each method is necessary for effective testing.
